THREAD-BOARD FOR SPINNING, TWISTING, AND'LIKE MACHINES,

To all whom it may concern:

Be it known that I, ALBERT H. MORTON, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Thread-Boards for Spinning, Twisting, and the llke Machines; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an i1nprovement in thread boards for Spinning, twisting and the like machines.

The object of the invention is to reorganize and improve the construction of thread boards, and to this end the invention consists in the thread board hereinafter de scribed and particularly defined in the claims.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 is an elevation of a thread board with the board in vertical position; Fig. 2 is a sectional plan on the line 22 of Fig. 1; Fig. 3 is a section on the line 3-3, Fig. 1; and Fig. 4 is a section on the line 4=t, Fig. 1.

Heretofore, when the dofiing rail was lifted, it sometimes happened that some of the thread boards fell over, with the result that when the dofling rail was lowered, the thread boards which had fallen over remained in turned-back position; this required the operative to turn each one of them down separately into normal or operative position.

The present invention contemplates providing means for holding the thread boards in and restoring them to operative position with relation to the dotting rail, or other support, after disturbance therefrom whet-her in dotting or in piecing, or otherwise.

Referring to the drawings, the thread board 1 carries at its outer end the thread guide or finger 2, and is supported at its inner end upon the thread board support 3 which is adapted to be bolted to the dofiing rail. The thread board is secured to the thread board support by means of the hinge pintle 4: which is received in ears 5 of the thread board 1 with a driving fit. This pintle is loosely received in the bearings 6 and 7 of the thread board support 3 so as to Specification of Letters Patent.

turn freely therein. The pintle is embraced by a spring 8 which at one end engages'the slot 9 in the pintle and'at the'other end engages the thread board support 3. The construction is such that when the thread board His-lifted it winds up the spring 8 and the lifting is accomplished against the resistance of the spring, so that when the lifting pressure upon the thread board is relieved, the spring returns the thread board to its normal or operative position with relation to the dotting rail.

In Fig. 3 is shown a portion of the thread board and its support, illustrating the position of the left-hand end of the spring 8;

Fig. 42 is a similar view looking in the opposite direction, showing the right-hand end of the spring 8 in engagement with the notch 9 in the pintle a, and both showing the thread board in its normal or operative position. The lugs 10 serve as stops to support the thread board in its normal or operative position, and act to limit the movement of the thread board under the influence of the spring 8 in the downward direction.

The thread board may be supported on a part attached to the doifing rail, as in the illustrated embodiment, or otherwise; so it will be understood that the term support, as used in the claims, is a comprehensive term indicating any form of support for the thread board.

This invention contributes to facility of attendance because the thread boards tend to hold themselves in operative position and are not required, either by reason of displacement in piecing or in dofling, to be returned to operative position, as they normally maintain their operative position with relation to the do'liing rail or the support therefor without any attention on the part of the operative;

The inexpensiveness and simplicity of the invention contribute to its value and utility.

The gist of the invention, broadly considered, resides in providing a thread board with means by virtue of which it is normally maintained in operative position with relation to the doffing rail or other support therefor.

The invention is not limited to the illustrated embodiment thereof.

Having thus described the invention, what is claimed is 1. A spinning frame having, in combination, a thread board, a thread board Support OFFICE.

upon Which the thread board is pivoted and means tending to turn the thread board on the pivot in the direction to hold it in its normal or operative position thereon, substantially as described.

2. A spinning frame having, in oo1nloination, a thread board, a thread board support upon which the thread board is pivoted and a spring connecting the thread board and support tending to turn the thread board in the direction to cause it to assume its normal or operative position thereon, substantially as described.

3. A spinning frame having, in combination, a thread board. a thread board support upon which the thread board is pivoted, a pintle forming the pivot connecting the thread board and thread board support, and a helical spring mounted upon the pintle and acting to hold the thread board in normal or operative position thereon, substantially as described.
